Methods and apparatus for calibrating and/or adjusting the arrangement of cameras in a camera pair

A method, comprising:

• operating first and second cameras of a camera pair, mounted on a camera mount and facing a calibration target, said calibration target being a physical object, said calibration target including a grid pattern to capture first and second images, respectively, of said grid pattern, said grid pattern including a plurality of grid elements, each grid element occupying an area of a grid, said grid pattern including subsets of grid elements of different colors;
• operating a processor to generate a calibration image by combining a first image captured by said first camera on a second image captured by the second camera;
• and
• displaying the generated calibration image.

An apparatus, comprising:

• a calibration target including a grid pattern, said calibration target being a physical object, said grid pattern including a plurality of grid elements, each grid element occupying an area of a grid, said plurality of grid elements including grid elements of a first color, grid elements of a second color, grid elements of a third color and grid elements of a fourth color, said first, second, third and fourth colors being different;
• a camera pair mount for supporting a camera pair facing said calibration target, said camera pair including a first camera and a second camera, said first and second cameras being positioned adjacent one another facing said calibration target;
• a display;
• and
• a processor configured to:
• generate a calibration image by combining a first image captured by said first camera with a second image captured by the second camera by superimposing the first image on the second image;
• and
• control the display to display the generated calibration image.
